For years we have seen holographic technology usually on the screen in science fiction TV shows and movies like Start Trek or Star Wars. Who doesn’t remember the scenes where RD2D is projecting a 3D holographic image of Princess Leia asking Obi Wan Kenobi for a help. In Star Trek we know that they used famed holodeck which had the technology to project many star ships. So when you see that type of technology in Hollywood movies, it looks easy. But, in real world it’s a whole another story. All the attempts usually end up looking as very primitive design. People are experimenting with many different methods, while some were successful others were not. Not long ago, one team from University of Tokyo managed to create first successful touchable holograms. Imagine that you have a hologram of little red ball in front of you, and you can actually interact with it. The ball itself was aware when you were getting near and it would try to bounce back. When this type of technology was announced for the first time it was being compared to computer holographic interface from movie Minority Report.
